KEYLESS PADLOCK.

Specification of Letters Patent.

Patented Oct. 27, 1908.

Application filed January 16, 1905. Serial No. 241,312.

To all whom it may concern:

Ee it known that I, GEORGE W. KONE, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful improvements in Keyless Padlocks,of which the following is a specification.

My invention relates to improvements in ocks.

It relates particularly to permutation padlocks in which the use of keysis dispensed with.

The object of my invention is to provide a keyless padlock of thecharacter described which is capable of being set to many combinations,which is reliable in operation, not easily4 disordered, is cheap tomanufacture, and which possesses great durability.

My invention provides a construction in which the operator may quicklychange the combinatiim.

1t provides further a construction of lock by which the operator mayeasily adjust the tumblers to the proper position for unlocking by theaid of the sense of feeling alone, thus enajbling one to unlock themechanism in the dart.

Other novel features are hereinafter fully i l? ig. d is an endelevation of the padlock with the cap and shackle removed. Fig. 5 is aside elevation of the padlock. Fig. 6 is a rear end view of a tumbler.Fig. 7 is an end view of the inner member of a tumbler.

Similar characters of vreference denote similar parts.

1 denotes the crown having a central tubular part 2 closed at its re arend and having a lateral opening 3 to receive the shackle 4, the inneror free end of which is notched to receive a slide bolt 5reciprocatively mounted in the tubular portion 2 of the crown l. Theslide bolt 5 preferably comprises a cup shaped body the bottom of whichis provided with a recess 6 adapted to receive therein the notched endof the shackle. A coiled spring 7 bears at one end against the slidebolt 5 and at the other end upon the inf ner side of the closed end ofthe crown 1.

The tension of the spring 7 is such as to normally force the slide bolt5 forward into engagement with the shackle.

Secured at one end forward of the opening 3 to the crown 1 is aconnecting member 8 comprising preferably a tubular post longitudinallyslotted at one side and having its other end externally screw threaded.Rotatively mounted on the screw threaded end ofthe post 8 is a cap 9 towhich the shackle 4L is pivoted. Reciprocatively mounted in the post ortube 8 and extending through the central portion of the cap 9 is amember comprising preferably a slidable bar having a series of lateralprojections 11 extending laterally through the slot 10 of the post 8,the slidable bar being denoted by 12. The rear end of the bar 12 isprovided with a projection 13 which enters a hole 14 in the bolt 5 andprevents rotation of the bolt 5 in the crown. In the outer end of thepost disposed diametrically opposite the slot 10 is a slot 15 in whichis mounted a projection 16 on the bar 12 which with the projections 11prevent rotation of the bar in the post.

The outer of the projections 11 is adapted when the bar 12 is not movedto enter a recess or hole 17 provided in the cap 9 and revente rotationof the cap on the post 8, but when the bar 12 is moved inward theprojection is withdrawn from the recess 17 and the cap may be unscrewedand detached from the ost to enable the operator to remove andD changethe combination of the tumblers.

The tumblers are rotatively mounted between the cap 9 and crown 1 andencircle the post 8 and bar 12. Each tumbler comprises an outer annularmember 18 preferably of cup like form and provided on its innerperiphery with a plurality of circularly arranged recesses 19 adapted toreceive a rearwardly extending projection 2O provided on the rear sideof the inner member 21, which is also preferably of annular cup likeform, the transverse or bottom portion of which is disposed so as toengage with and prevent movement of the bar12 when the inner member isdisposed in any other than a certain position. The bottom of each innermember of each tumbler is provided with a slot 22 through which theouter adjacent proj ection 11 may pass when all the tumblers are icodisposed so that the slots 22 are in alinement with the ,projections I11. When so positioned the bar 12 may be moved, thus forcing back theslide bolt 5 against the pressure of the spring 7 and releasing theshackle 4 from the bolt 5 and permitting the withdrawal of the shacklefrom the opening 3. Vhen the bar 12 is moved inward the outer projection11 is withdrawn from the hole or recess 17 and the cap can be removed asabove described. The tumblers may then be removed from the post 8 andthe inner member 21 of each turned to any desired position.

The outer member 18 of each tumbler is provided with a series oftransverse grooves 23 disposed parallel with the axis of the member andarranged at equal intervals around its outer periphery thus dividing theperiphery into a series of raised portions corresponding in number tothe number of recesses 19. One of said raised portions may be providedwith a projection 24 which furnishes a starting point by which theoperator may by feeling properly rotate the tumbler to the positionrequired for unlocking the padlock. For convenience another projection25 differing in coniiguration from the projection 24 may be provided onthe raised portion disposed diametrically opposite the one havingthereon the projection 24. The projection 24 may be pointed and the projection 25 flattened for effecting a ready recog nition between them. Theother raised portions on the outer member 18 may be numbered or providedwith other suitable distinguishing devices. The periphery of the crown 1may be provided with one or more grooves 26 to serve as guides forproperly locating the different tumblers. VV hen disposed in the lockedposition as shown in Fig. 1, the projections 11 lie respectively forwardof the bottom of the inner members 21, thus permitting free rotation ofthe tumblers to and fro.

The outer members are rotatively iitted respectively in each other andin the crown, a shoulder being provided on the rear ond of each outermember for this purpose. The cap 9 is mounted in the outer or forwardone of the outer members and prevents forward movement of the innermember of the outer tumbler, the outer members of the rear tumblerspreventing forward movement of the other inner members 21.

To unlock the padlock, the combination being known to the operator, heturns the tumblers to positions in which the slotted positions of theinner members 21 will be in alinement with the projections of the bar12. The bar 12 is then moved rearwardly, thus moving the bolt 5 andreleasing therefrom the shackle 4. To lock the device, it is butnecessary to insert the free end of the shackle into the opening 3. Theshackle will force the bolt 5 rearwardly until the projection at therear edge of the notched end of the shackle is opposite the hole orrecess 6, at which time the spring 7 will force the bolt 5 forward andcausing the bolt to enter the notch in the shackle.
